volu e 21. 62-141) ,rator shell II. The amount of insulation for. the

water cooler is consequently materially reduced.-- -If the cooler is to be ,used for cooling water, either a bottle .or demijohn may be used for supplying water to the receptacle formed by the 5 evaporator shell or the device maybe connected directly with the citywaler supply. If a bottle is used, the receptacle 1! is covered with a plate ll providedwitha throat or upwardly extending portion-Ila for receiving the neck of the bottle. the upper extremity of said throat being. pro.- vided with an annular groove or recess ll adapted to receive a gasket-Ill of rubber or other soft material. The plate orhead It may be secured in position in any desired manner, in the present instance bolts II being employed, and by means of these bolts the connecting brackets Ila and the evaporator shell'are rigidly'connected. In order nto withdraw liquid from the reservoir II, a discharge pipe I! has one end connected to the lower no central portion of the same and has its outer end provided with a faucet i8. r The above described construction constitutes an operative refrigerating unit for cooling liquid and the parts areexposedand readily ac-. as

cessible for examination or service. 1

A suitable casing for the above described mechanism consists of an easily detachable shell 2| of metalor like material slipped down-over the entire framework until it rests upon the gasket fl after which it may be secured in position by means of screws or other fastening elements II. The shell 24 is provided inthe central portion of its top with-an opening surrounded by a flange It inwhichfiis disposed a gasket .21 upon-which as tests a bottle II. If it is notdesired to use a bottle. a solid head, not shown, may be usedin lieu of the head II. Also, with asolid head, the .opening inthe upper portion of" the shell may be 7 dispensed wither maybecovered by a suitable to cover. I v i The shell fl is provided in itsi'ront' withan openinm through which the outer ends of the 'tubing If projects. Through this opening the end ofthe tubing may be pulled. and the es tubing is provided with one orgmore extra turns to facilitate such manipulation. when pulledendof the tubing is aoce'ssible for the attachmentofthefaueet.

In the construction shown, a plate 2. is at-, so taehed to the fancet-andthis plate is secured to by means of screwsor other fastening elements It. 'lhis construction permits the utilisationgof a faucet which-ls largerthanthe to empty its contents.
